INK BOTTLE Filed Dec. 2, 1941 VINVENTOR" Patented June 16, 1942 4 UNITED STATES PATENT OFFICE INK BOTTLE Kai-Reinecke, Brooklyn, N. Y.

Application December 2, 1941, Serial No. 421,268

2 Claims.

This invention relates to improvements in ink dispensing devices used in combination with ordinary ink bottles for providing an ink level which can be reached to fill a pen when the level of the ink in the bottle has sunk beyond ordinary reach. The object of the invention is to provide such an ink dispensing device in the form of a glass tube to be inserted in an ink bottle to provide the desired ink level by merely inverting the tube. The tube may be a new article of manufacture to be inserted initially in the bottle or it may be a separate article to be inserted when necessary. The invention is embodied in an ink dispensing device constructed and arranged as hereinafter explained and as illustrated in the accompanying drawing in which- Fig. 1 is a sectional view of the tube which may be made of glass or other suitable material.

Fig. 2 shows the tube inserted in the bottle.

Fig. 3 shows the tube and bottle inverted.

Fig. 4 shows the bottle right end up.

Referring to Figs. 1-4 the invention may be embodied in a glass tube of suitable length and diameter to be placed within the ink bottle. The tube It] has formed therein a cup II with a closed bottom l2. The length of the cup is designed to hold enough ink to fill a fountain pen. The cup space has two air holes I3 and I4, and below the cup the tube has two air holes Hiand The ink bottle ll may have the tube inserted initially and then of course the pens are filled from the cup ll. When the latter has been emptied, Fig. 2, the ink level is beyond reach.

Then the bottle is closed with its cap 19 and inverted, Fig. 3. Ink will now flow into the cup as indicated at 29. The air in the cup escapes through the holes l3 or M, or one of these holes if only one hole is provided as may be the case. Thus a quantity of ink is trapped in the cup and is available for pen filling purposes when the bottle is turned right end up, Fig. 4, the ink level being even with the hole l3. When the cup is empty, the bottle is closed and the operation repeated and so forth until all the ink in the bottle has been used. Once the tube has been inserted and the cap put on, as it will be in any event to avoid evaporation and dirt, the operation requires nothing more than inverting the bottle, up-ending it and removing the cap. As a separate article of manufacture the tube may be used with other ink bottles.

The lower portion 2| of the tube serves as a support. The holes 15 and I6, or at least one of them, lets the air out of the tube so that ink may flow readily into the tube and thus less ink will be displaced when the tube is inserted. The tube is preferably of slightly less length than from the underside of the bottle cap to the bottom to provide a loose fit so that the ink can readily flow into the cup at the end of the tube as indicated at 22, Fig. 3. It is also desirable to provide a centering support l8 in the bottom of the bottle. The upper end of the tube engages the side wall of the bottle neck to prevent lateral displacement of the tube as will be understood.

I claim:

1. As a new article of manufacture, a tube insertible in an ink bottle, said tube reaching from the mouth of the bottle to the bottom thereof in non-attached relation to the bottle, one end of said tube engaging the side wall of the bottle neck to avoid lateral displacement of the tube within the bottle, a solid partition in said tube forming a cup therein at one end to receive by complete inversion of the said bottle and tube a predetermined quantity of ink for pen filling purposes when said bottle and tube are re-inverted and an air hole in the wall of said cup spaced a distance above said partition to allow air to escape from said cup when the tube is inverted as aforesaid.

2. As a new article of manufacture, a tube insertible in an ink bottle, said tube reaching from the mouth of the bottle to the bottom thereof, one end of said tube engaging the side wall of the bottle neck to avoid lateral displacement of the tube within the bottle, a solid partition in said tube forming a cup therein at one end thereof to receive by complete inversion of said bottle and tube a predetermined quantity of ink for pen filling purposes when said bottle and tube are re-inverted, the ink passing into the cup through the end of the tube when the same is inverted, an air hole in the wall of the cup spaced a distance above said partition and a distance below the end of the tube to allow air to escape from the cup when the tube is inverted, and an air hole in the wall of the tube below said partition to allow air to escape from the lower portion of the tube.
